Definitions

  • the present invention provides a method for blanketing the surface of molten metal that avoids the afore-mentioned disadvantages.
  • a specific requirement is that the application of the blanket material to the surface of the molten metal should cause as little dust formation as possible.
  • the blanket material used should have good heat insulation properties and be convenient to spread over the surface of the molten metal.
  • the blanket material according to the invention starts to spread by itself to form an even layer on the entire surface of the molten metal.
  • This behaviour which is extremely advantageous for the process covered by the invention, is primarily based on the close grain-size distribution of the synthetic zeolite material.
  • the flow characteristics of the blanket material are further improved, if these grains are essentially sphere-shaped and if their surface is as smooth as possible.
  • the blanket material can be applied particularly conveniently to the surface of the molten metal in plastic polymer bag portion packs. Due to the high temperatures in the area above the molten metal, which are well over 1000° C., the plastic polymer bags burn instantly. Subsequently the blanket material spreads by itself over the surface of the molten metal owing to its good flow properties. In this process, dust formation is effectively prevented, due to the fact that the grains of the blanket material according to the invention has a grain-size of at least 30 ⁇ m in diameter.
